Apologies, the Challenger name comes out of the recipe development of this beer. I spent 3 to 5 years trying to develop a well balanced ESB that is easy drink and but still some uniqueness about it without taking anything away from the style. First public outing for this was the Adelaide Mash Brewers ESB challenge which it was the winner. Last two years it has won 1st place at SABSOSA in the Bitters section, unfortunately it hasn't repeated the same success at a Nationals level.
So to me it's my Challenger, the beer I like to put up there in comps, it my favourite beer I brew and it enjoy by my mate too and tastes great through a hand pump too
